Many great rivers flow toward the equator. The sediments that they carry, increases the time of rotation of the earth about its own axis.
The angular momentum of the earth about its rotation axis is conserved.

A

Statement-1 is True, Statement-2 is Ture , Statement -2 is a correct explanation for statement -1.

B

Statement-1 is True, Statement-2 is True , Statement-2 is NOT a correct explanation fro Statement -1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Verified by Experts

The correct Answer is:
A
because Sediment deposited at the equator (away from axis of rotation) increases the moment of inertia (not mass) of the Earth. Since `I omega = constant, omega` decreases and thus `I = (2 pi)/(omega)` increases.
